About

Mathematician turned cryptographer turned product lead. I went from abstract algebra and measure theory at METU to building and leading AI-native platforms used by hundreds of thousands of people.

I'm starting a Cryptography M.Sc. at METU now. Honestly, the part I like most isn't the theory on paper — it's getting hard math to actually work inside something people use every day.
